Description

Technical Field

[0001] The utility model relates to the technical field of waterproof engineering, in particular to a rubber waterstop node connected with a non-curing rubber asphalt waterproof coating. Background Art

[0002] Rubber waterstop is a waterstop material made of natural rubber or various synthetic rubber as the main raw materials, mixed with various additives and fillers, and made through processes such as plasticization, mixing, calendering and vulcanization. Rubber waterstop has good elasticity, wear resistance, aging resistance and tear resistance, strong deformation adaptability and good waterproof performance. It is usually used in the construction of basement exterior walls and post-casting strips.

[0003] The connection of rubber waterstop nodes has always been a common problem in engineering. The connection of waterstops is mainly divided into two methods: cold bonding method and hot vulcanization connection method: (1) On-site hot bonding vulcanization method uses hot vulcanization molds and raw rubber sheets that match the waterstop to vulcanize and hot-joint on-site, and the joint effect is good. This method requires professional equipment and skilled operators. The construction cost is high and the on-site construction is difficult. It is not applicable to projects with low profit costs. (2) The cold glue bonding method uses a special cold bonding glue for rubber waterstops and an overlap method to grind the cross-section of the rubber waterstop to be jointed by a grinder to 250~300mm, apply glue and then compact. This method has the advantages of fast solidification, convenient construction, time saving and labor saving. However, the construction site environment is complex. When the temperature is low, the reliability of the connection node is reduced due to the construction load. Due to the different linear expansion coefficients of concrete and rubber waterstops, the rubber waterstop nodes buried in the concrete may be affected by alternating tensile and compressive stresses with temperature changes, fatigue damage occurs at the nodes, and the waterstop effect is greatly reduced. Utility Model Content

[0037] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0038] Example:

[0039] like Figure 1-2 As shown, the present application provides a rubber waterstop node connected with a non-curing rubber asphalt waterproof coating, which ensures the stability of the rubber waterstop structure, thereby ensuring the water-stopping effect;

[0040] The specific structure of this application includes:

[0041] Waterstop unit 1;

[0042] The tray unit 2 is arranged at the bottom of the water stop unit 1, and the tray unit 2 wraps the water stop unit 1 to prevent the material inside the water stop unit 1 from flowing out and causing pollution;

[0043] The water stop unit 1 comprises:

[0044] Upper rubber water stop 101;

[0045] A lower rubber water stop 102, with a gap 103 between the lower rubber water stop 102 and the upper rubber water stop 101;

[0046] The adhesive layer 104 is filled in the gap 103; in the present application, the waterstop unit 1 is divided into three parts. Compared with the existing upper and lower waterstop structures, the present application adds an adhesive layer 104, which is used to achieve the bonding effect, thereby ensuring the stability of the waterstop unit 1 structure.

[0047] Specifically, the bonding layer 104 in the present application is a non-curing rubber asphalt waterproof coating layer; that is, the present application uses non-curing rubber asphalt waterproof coating for connection. Non-curing rubber asphalt waterproof coating has the characteristics of always maintaining a viscous colloid state, and at the same time has the advantages of strong self-healing ability, sticking to the touch, difficult to peel off, and still having good bonding properties under low temperature conditions. When used as a bonding material at the node, the material always maintains the characteristics of a viscous glue state, so that under the action of fatigue loads, large shrinkage deformation is allowed at the node. The strong self-healing characteristics of the cured rubber asphalt waterproof coating can well prevent fatigue damage at the node.

[0048] The thickness of the adhesive layer 104 is 5 mm, which can ensure the stability of the structure of the waterstop unit 1 without affecting the structure of the waterstop unit 1.

[0049] In one embodiment, the tray unit 2 is a metal tray, which can better support the water stop unit and prevent the adhesive layer 104 from flowing out during assembly, thereby contaminating the bottom distributed steel bars and affecting the adhesion between the steel bars and concrete.

[0050] In yet another embodiment, the tray unit 2 comprises:

[0051] Transverse section 201;

[0052] Two vertical sections 202, the vertical sections 202 are respectively arranged at the two ends of the transverse section 201; the tray unit 2 in the present application is divided into two parts to form a groove structure, so as to ensure that the waterstop unit 1 is stably located inside the tray unit.

[0053] Specifically, the height of the vertical section 202 is higher than the height of the waterstop unit 1 , so that the adhesive layer can be prevented from flowing out of the tray unit 2 .

[0054] In another embodiment, an upper concave portion 105 is provided in the middle of the upper rubber water stop strip 101;

[0055] The lower rubber water stop strip 102 is provided with a lower concave portion 106 at a position corresponding to the upper concave portion 105;

[0056] The upper concave portion 105 and the lower concave portion 106 cooperate and combine to form a ring shape, which can ensure a water-stopping effect.

[0057] In the specification of the present utility model, a lot of specific details are described. However, it is understood that the embodiments of the present utility model can be practiced without these specific details. In some examples, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this specification.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
